Kodak RA4 at 20deg C

Matt5791 · May 23, 2009

I've tried to search, but I'm sure I saw someone say that you can use the Kodak RA4 chemistry at room temperature - if this is the case does anyone have any development times for this? - I've looked at Kodak's website but can't find anything.

Many thanks,

Matt

Matt,

2 minutes has been recommended. With the note that you may need to balance out some increased yellow.

Thanks for that Tom.

Matt,

I thought you run a Durst Printo?

It was PE (Ron Mowrey) here on APUG that does that. Tray processing RA-4 at room temp. using developer replenisher without any starter.

woops. I use developer replenisher with starter to make the tank solution. I use that in trays at whatever temperature my laundry room happens to be at. The development is fairly rapid. 2-3 minutes is the recommended time but I get results with less. Blix time is something like 4 minutes and then the usual RC paper wash of 2-5 minutes.

I do - I was just curious about the flexibility of the Kodak chemistry.

Best regards,
Matt

I use the Kodak 10 liter dev/rep and blix kits without the starter solution, 2 min in the dev and 2 in the blix. I get very consistent results at 20-21.5C, using one shot in drums. No noticeable colour shift even when the same neg is printed 10 weeks apart in the same batch mix of working solutions.

Use RA-RT developer replenisher for the developer. Use 2' at 20 deg C.
